如何比较两个数组并删除从一个匹配的元素为下一个循环？ [英] How to compare two arrays and remove matching elements from one for the next loop?

问题描述

否则怎么可能你比较两个数组（$ A $和B），并减少匹配元素出第一至preP超过数组$ A下一个循环？

How else might you compare two arrays ($A and $B )and reduce matching elements out of the first to prep for the next loop over the array $A?

$A = array(1,2,3,4,5,6,7,8);
$B = array(1,2,3,4);

$C = array_intersect($A,$B);  //equals (1,2,3,4)
$A = array_diff($A,$B);       //equals (5,6,7,8)

这是最简单的方法还是有使用，我没有想到的另一个函数的方法吗？我的目标是有，我可以遍历，拉出的相关内容组（我在别处定义的那些关系），直到​​数组返回false数组。

Is this the simplest way or is there a way to use another function that I haven't thought of? My goal is to have an array that I can loop over, pulling out groups of related content (I have defined those relationships elsewhere) until the array returns false.

推荐答案

您已经得到它。只要使用和array_diff或array_intersect。没有什么比这更容易。

You've got it. Just use array_diff or array_intersect. Doesn't get much easier than that.
